Compounds of formula (II):

where R¹ and R² are as defined above for a compound of formula (I) and Y is halogen, hydroxy or C₁₋₅ alkoxy, are useful as intermediates in the preparation of compounds of formula (I).

Some compounds of formula (II) are already known in the literature [B. Iddon et al. J. Chem. Soc. Perkin Trans. 1, 1341 (1996); M. Begtrup et al., Acta Chemica Scald., 19, 2022 (1965); D. R. Buckle et al., J. Chem. Res, Syn. 10, 292 (1982); and A. Peratoner et al., Sci. Fis. Mat. Nat. Rend 5, 16 (1907)] but others are novel.

Therefore, in another aspect the present invention provides a compound of formula (II) where R¹ and R² are as defined above for a compound of formula (I) and Y is halogen, hydroxy or C₁₋₅ alkoxy; provided that when R¹ is chloro and R² is 4-CH₃O—C₆H₄—CH₂—, Y is not C₂H₅O; when R¹ is CH₃O and R² is CH₃, Y is not C₂H₅O; when R¹ is bromo and R² is CH₃OCH₂, Y is not CH₃O; and when R¹ is CH₃ and R² is C₂H₅, Y is not OH.

Preferably Y is hydroxy, chloro, fluoro or C₁₋₃ alkoxy.

Some compounds of formula (IIIa) are also novel but some are described in the literature [see, for example, L. A Paquette et al., J. Amer. Chem Soc. 99, 3734 (1977); H. Plieninger et al., Chem. Ber. 109, 2121 (1976); Kasansski et al., Zh. Obshch. Khim. (1959), 29, 2588; and A. J. Kirby et al., J. Chem. Soc., Perkin Trans. 2, 1997, 1081].

Anilines of formula (IIIa) are novel when R¹³, R¹⁴, R¹⁵, R¹⁶, Q and X are as defined above for a compound of formula (I); provided that when R¹³, R¹⁴, R¹⁵ and R¹⁶ are each H then X is not CH₂ when Q is a double bond and X is not CH₂CH₂ when Q is a single bond or a double bond; and when R¹³ is CH₃, R¹⁴ is OCH₃ and R¹⁵ and R¹⁶ are both H then X is not CH₂CH₂ when Q is a single bond.

Therefore, in a further aspect, the present invention provides a compound of formula (IIIa) where R¹³, R¹⁴, R¹⁵, R¹⁶, Q and X are as defined above for a compound of formula (I); provided that when R¹³, R¹⁴, R¹⁵ and R¹⁶ are each H then X is not CH₂ when Q is a double bond and X is not CH₂CH₂ when Q is a single bond or a double bond; and when R¹³ is CH₃, R¹⁴ is OCH₃ and R¹⁵ and R¹⁶ are both H then X is not CH₂CH₂ when Q is a single bond.

The compounds of formula (I), (II) and (IIIa) may exist as different geometric or optical isomers or in different tautomeric forms. This invention covers, for each formula, all such isomers and tautomers and mixtures thereof in all proportions as well as isotopic forms such as deuterated compounds.

The compounds according to formula (I) may be prepared according to the following reaction schemes.

(a) Preparation of a Compound of Formula (II).

Schemes 1, 2 and 3 demonstrate that a compound of formula E, H, K, L, N, O, P, R, S, T, U, V, W, Y or Z [where R¹ and R² are as defined above for formula (II); and R′ is C₁₋₅ alkyl] {each of which is a compound of formula (II), as defined above} may be prepared by a reaction sequence starting with a 1,2,3-triazole-4,5-dicarboxylic acid diester of formula A [Y. Tanaka et al., Tetrahedron, 29, 3271 (1973)] [where each R′ is, independently, C₁₋₅ alkyl] (preferably the dimethyl ester).

Treatment of A with an alkylating agent [such as R²-halo (where R² is as defined above for formula (U); and halo is preferably iodo) or an appropriate sulphate, sulphonate or carbonate ester] in the presence of a base [such as K₂CO₃, Na₂CO₃ or NEt₃] in a suitable solvent [such as acetonitrile, DMF or dimethylacetamide] at ambient to elevated temperatures furnishes a mixture of regioisomers, of formulae B and C, which may be separated by conventional methods. Saponification of a compound of formula B with up to one equivalent of a base [such as KOH, NaOH or LiOH] in a protic solvent [such as methanol], preferably under reflux conditions, provides a mono-ester of formula D. Subsequent reaction of a compound of formula D with a fluorinating agent [such as DAST (diethylamino sulphur trifloride) or, preferably, SF₄] in the presence of hydrofluoric acid gives a 5-CF₃-1,2,3-triazole-4-carboxylic acid ester of formula E.

Alternatively, treatment of a compound of formula D with a chlorinating agent [such as thionyl chloride or phosgene] under standard conditions results in an acid chloride of formula F which may be reduced catalytically in an inert solvent [for example ethyl acetate or THF] in the presence of a base [for example Hünig base] to give an aldehyde-ester of formula G (modified Rosenmund conditions). Fluorination of a compound of formula G by means of DAST, dimethoxy-DAST or SF₄ in the presence of hydrofluoric acid, optionally with solvent, preferably at elevated temperatures, forms a 5-difluoromethyl-1,2,3-triazole-4-carboxylic acid ester of formula H.

Metal hydride reduction of a compound of formula G [for example by NaBH₄ or LiBH₄] in methanol provides a 5-hydroxymethyl-1,2,3-triazole of formula J, from which a 5-fluoromethyl derivative of formula K may be obtained by fluorination under mild conditions, preferably with DAST at low temperatures (0 to −78° C.) in an inert solvent [such as dichloromethane].

Alternatively, hydride reduction of a compound of formula J by conventional methods [for example via its mesylate, tosylate or iodide] results in a 5-methyl-1,2,3-triazole of formula L.

Chlorination of compound of formula D [for example by thionyl chloride] followed by treatment with ammonia, preferably in a protic solvent [such as water, methanol or ethanol] furnishes an amide of formula M from which a 5-cyano-1,2,3-triazole of formula N may be obtained by means of a dehydrating agent [such as phosphorylchloride].

Further transformations to prepare a compound of formula (II) [where R¹ and R² are as defined above for formula (I); Y is OR′ and R′ is C₁₋₅ alkyl] include a Hofmann rearrangement of an amide of formula M with NaOBr or NaOCl in the presence of NaOH to give a 5-amino-1,2,3-triazole of formula O.

Diazotation of a compound of formula O by means of sodium nitrite under aqueous acidic conditions [for example sulphuric acid] or with a nitrite ester [for example (i)-amyl nitrite] in an organic solvent [for example acetone, dichloromethane or THF] in the presence of a halogenide [such as CuCl or CuBr] gives a 5-halo-1,2,3-triazole of formula P [where halo is Cl or Br] which on treatment with a fluorinating agent [such as KF or CsF], preferably in DMF or N-methylpyrrolidone at elevated temperatures, results in a 5-fluoro-1,2,3-triazole of formula V.

By diazotation of a compound of formula O and subsequent acidic aqueous hydrolysis under heating, a 5-hydroxy-1,2,3-triazole of formula Q may be obtained. Treatment of a compound of formula Q with an alkylating agent [such as methyl iodide, dimethylsulphate or dimethylcarbonate] and a base [for example NaH, K₂CO₃ or Na₂CO₃] in a polar solvent [for example DMF, DMSO or CH₃CN] gives a 5-methoxy-1,2,3-triazole of formula R which may be converted to a trichloromethoxy derivative of formula S with a chlorinating agent [such as chlorine] in the presence of azoisobutyronitrile (AEBN) or ultra-violet irradiation at elevated temperature. By treatment of a compound of formula S with a fluorinating agent [for example KF or SbF₃] a 5-trifluoromethoxy-1,2,3-triazole of formula T may be prepared.

Oxidation of a compound of formula O with [for example sodium perborate] or treatment according to A. Sudalai et al. [Angew. Chem. Int. Ed. 40, 405 (2001)] leads to a 5-nitro derivative of formula U. Alternatively, a compound of formula U may also be obtained by treatment of a compound of formula P or V with NaNO₂ in an polar solvent [such as DMF, sulpholane or N-methylpyrrolidone] at elevated temperatures.

Transformations of a compound of formula (II′) [where R¹ and R² are as defined in formula (I); Y is OR′; and R′ is C₁₋₅ alkyl] to give a compound of formula (II) [where R¹ and R² are as defined in formula (I) and Y is halo or hydroxy] includes saponification with a base [such as KOH or NaOH] in a protic solvent [such as methanol, ethanol or water], at ambient or elevated temperature to give a 1,2,3-triazole-4-carboxylic acid of formula W. Chlorination of a compound of formula W under standard conditions [for example with thionyl chloride, phosgene or oxalyl chloride] yields an acid chloride of formula Y.

Fluorination of a compound of formula W with DAST or SF₄ under mild conditions [low to ambient temperatures], preferably in an inert solvent [such as dichloromethane] gives an acid fluoride of formula Z.

(b) Preparation of a Compound of Formula (III).

A compound of formula (III) H₂N-A  (III) where A is as defined above for a compound of formula (I), is useful as an intermediate in the preparation of a compound of formula (I).

Most o-substituted amino-aryls and amino-heteroaryls of formula (III) are known from the literature, but some are novel.

A compound of formula (IIIa) may be obtained according to scheme 4:

Treatment of an orthlo-substituted nitrobenzonorbornadiene of formula AA (where R¹³, R¹⁴, R¹⁵, R¹⁶ and X are as defined above for a compound of formula (I)) [obtained through Diels-Alder addition of an in situ generated benzyne, for example, starting from a 6-nitroanthranilic acid as described by L. Paquette et al, J. Amer. Chem. Soc. 99, 3734 (1977) or from other suitable benzyne precursers (see H. Pellissier et al. Tetrahedron, 59, 701 (2003) with a 5-7 membered cyclic 1,4-diene according to, or by analogy to, L. Paquette et al, J. Amer. Chem. Soc. 99, 3734 (1977), D. Gravel et al. Can. J. Chem. 69, 1193 (1991), J. R. Malpass et al. Tetrahedron, 48, 861 (1992), D. E. Lewis et al. Synthetic Communications, 23, 993 (1993), R. N. Warrener et al. Molecules, 6, 353 (2001), R. N. Warrener et al. Molecules, 6, 194 (2001) or I. Fleming et al. J. Chem. Soc., Perkin Trans.], 2645 (1998)] with Zn, in the presence of ammonium chloride or an aluminium amalgam, in a protic solvent [such ethanol or water] gives an aniline of formula CC, whilst catalytic hydrogenation of a compound of formula AA with, for example, RaNi, Pd/C or Rh/C in the presence of a solvent [for example THF, ethyl acetate, methanol or ethanol] affords an aniline of formula BB.

Compounds of formula (IIIb)

where R⁶ is an aliphatic or alicyclic, saturated or unsaturated group [in which the group contains three to thirteen carbon atoms and at least one silicon atom and, optionally, one to three heteroatoms, each independently selected from oxygen, nitrogen and sulphur, and the group is optionally substituted by up to four independently selected halogen atoms] and R⁷⁻¹⁰ are as defined in formula (I) may be prepared by analogy with literature examples.

Another group of anilines comprises compounds of formula (IIIc)

where R′ represents C₂₋₄ alkyl, C₂₋₄ haloalkyl or C₃₋₆ cycloalkyl (itself optionally substituted by up to 3 substituents, independently selected from halo, C₁₋₃ alkyl, C₁₋₃ haloalkyl and C₁₋₄ haloalkoxy).

A compound of formula (IIIc) may be prepared by a reaction sequence starting with a crossed aldol condensation of benzaldehyde with a ketone of formula CH₃C(O)R′ [where R′ is as defined above for a compound of formula (IIIc)] in the presence of NaOH or KOH in a solvent (such as water or ethanol) and usually under reflux conditions or alternatively by reaction of benzaldehyde with a Wittig reagent under standard conditions. The resulting α,β-unsaturated ketone of formula (IV) [where R′ is as defined above for a compound (IIIc)]:

may then be converted into a compound of formula (V′) [where R′ is as defined above for a compound (IIIc)]:

by reacting first with hydrazine hydrate in ethanol under reflux conditions and then heating (in the range of from 150 to 250° C.) in the presence of KOH (distilling off the solvent). After nitration with HNO₃—H₂O or HNO₃-acetic anhydride in a cooled vessel (in the range of from −30° C. to 0° C.), the resulting o/p-mixture of a nitrobenzene of formula (VI) [where R′ is as defined above for a compound (IIIc)]:

may then be separated and catalytically reduced (Pt/C/H₂ or Ra—Ni/H₂) in a solvent (such as methanol, ethanol of THF) at ambient temperature to give a compound of formula (IIIc).

Alternatively the synthesis of a compound of formula (IIId) [where R′^(a) is hydrogen or methyl]

may be accomplished by a reaction sequence started by a Wittig reaction of o-nitrobenzaldehyde with an ylide, prepared from a cyclopropylmethyltriphenylphosphonium bromide in the presence of a strong base [such as NaH] in a solvent [such as DMSO], in the range of 0-85° C. The resulting E/Z-mixture of a compound of formula (VII)

[where R′^(a) is hydrogen or methyl] may be converted to a compound of formula (VIII)

by the application of the Simmons Smith reaction (Zn—Cu, CH₂I₂, ether as a solvent) to the olefin group of a compound of formula (VII) to give a compound of formula (VIII). The reduction of the nitro moiety of a compound of formula (VIII) to give a compound of formula (IIIc) may be performed by using the same conditions as described above for a compound of formula (VI). (c) Preparation of a Compound of Formula (I).

A compound of formula (I) [where A, R¹ and R² are as defined above and R³ is H] may be synthesized by reacting a compound of formula (II′) [where R¹ and R² are as defined above and R′ is C₁₋₅ alkyl] with an aniline of formula (III) [where A is as defined above for a compound of formula (I)] in the presence of NaN(TMS)₂ at −10° C. to ambient temperature, preferably in dry THF, as described by J. Wang et al., Synlett, 2001, 1485.

Alternatively, a compound of formula (I) [where A, R¹ and R² are as defined above and R³ is H] may be prepared by reacting a compound of formula (II) [where R¹ and R² are as defined above and Y is OH] with a compound of formula (III) [where A is as defined above for a compound of formula (I)] in the presence of an activating agent [such as BOP-Cl] and two equivalents of a base [such as NEt₃] or by reacting a compound of formula (II) [where Y is Cl, Br or F] with a compound of formula (III) in the presence of one equivalent of a base [such as NEt₃, NaHCO₃, KHCO₃, Na₂CO₃ or K₂CO₃] in a solvent [such as dichloromethane, ethyl acetate or DMF] preferably at −10 to 30° C.

A compound of formula (I) [where R³ is as defined above for formula (I), except that it is not hydrogen] may be prepared by reacting a compound of formula (I) [where R³ is hydrogen] with a species Y—R³ [where R³ is as defined for formula (I), except that it is not hydrogen; and Y is halogen, preferably Cl, Br or I; or Y is such that Y—R³ is an anhydride: that is, when R³ is COR*, Y is OCOR*] in the presence of a base [for example NaH, NEt₃, NaHCO₃ or K₂CO₃] in an appropriate solvent [such as ethyl acetate] or in a biphasic mixture [such as dichloromethane/water mixturte], at −10 to 30° C.

Surprisingly, it has now been found that the novel compounds of formula (I) have, for practical purposes, a very advantageous spectrum of activities for protecting plants against diseases that are caused by fungi as well as by bacteria and viruses.

The compounds of formula (I) can be used in the agricultural sector and related fields of use as active ingredients for controlling plant pests. The novel compounds are distinguished by excellent activity at low rates of application, by being well tolerated by plants and by being environmentally safe. They have very useful curative, preventive and systemic properties and are used for protecting numerous cultivated plants. The compounds of formula I can be used to inhibit or destroy the pests that occur on plants or parts of plants (fruit, blossoms, leaves, stems, tubers, roots) of different crops of useful plants, while at the same time protecting also those parts of the plants that grow later, for example from phytopathogenic microorganisms.

It is also possible to use compounds of formula (I) as dressing agents for the treatment of plant propagation material, in particular of seeds (fruit, tubers, grains) and plant cuttings (e.g. rice), for the protection against fungal infections as well as against phytopathogenic fungi occurring in the soil.

Furthermore the compounds according to present invention may be used for controlling fungi in related areas, for example in the protection of technical materials, including wood and wood related technical products, in food storage, in hygiene management, etc.

The compounds of formula (I) are, for example, effective against the phytopathogenic fungi of the following classes: Fungi imperfecti (e.g. Botrytis, Pyricularia, Helminthosporium, Fusarium, Septoria, Cercospora and Altemaria) and Basidiomycetes (e.g. Rhizoctonia, Hemileia, Puccinia). Additionally, they are also effective against the Ascomycetes classes (e.g. Venturia and Erysiphe, Podosphaera, Monilinia, Uncinula) and of the Oomycetes classes (e.g. Phytophthora, Pythium, Plasmopara). Outstanding activity has been observed against powdery mildew (Erysiphe spp.). Furthermore, the novel compounds of formula I are effective against phytopathogenic bacteria and viruses (e.g. against Xanthomonas spp, Pseudomonas spp, Erwinia amylovora as well as against the tobacco mosaic virus).

Within the scope of present invention, target crops to be protected typically comprise the following species of plants: cereal (wheat, barley, rye, oat, rice, maize, sorghum and related species); beet (sugar beet and fodder beet); pomes, drupes and soft fruit (apples, pears, plums, peaches, almonds, cherries, strawberries, raspberries and blackberries); leguminous plants (beans, lentils, peas, soybeans); oil plants (rape, mustard, poppy, olives, sunflowers, coconut, castor oil plants, cocoa beans, groundnuts); cucumber plants (pumpkins, cucumbers, melons); fibre plants (cotton, flax, hemp, jute); citrus fruit (oranges, lemons, grapefruit, mandarins); vegetables (spinach, lettuce, asparagus, cabbages, carrots, onions, tomatoes, potatoes, paprika); lauraceae (avocado, cinnamomum, camphor) or plants such as tobacco, nuts, coffee, eggplants, sugar cane, tea, pepper, vines, hops, bananas and natural rubber plants, as well as ornamentals.

The compounds of formula (I) are used in unmodified form or, preferably, together with the adjuvants conventionally employed in the art of formulation. To this end they are conveniently formulated in known manner to emulsifiable concentrates, coatable pastes, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granulates, and also encapsulations e.g. in polymeric substances. As with the type of the compositions, the methods of application, such as spraying, atomising, dusting, scattering, coating or pouring, are chosen in accordance with the intended objectives and the prevailing circumstances. The compositions may also contain further adjuvants such as stabilizers, antifoams, viscosity regulators, binders or tackifiers as well as fertilizers, micronutrient donors or other formulations for obtaining special effects.

Suitable carriers and adjuvants can be solid or liquid and are substances useful in formulation technology, e.g. natural or regenerated mineral substances, solvents, dispersants, wetting agents, tackifiers, thickeners, binders or fertilizers. Such carriers are for example described in WO97/33890.

The compounds of formula (I) are normally used in the form of compositions and can be applied to the crop area or plant to be treated, simultaneously or in succession with further compounds. These further compounds can be e.g. fertilizers or micronutrient donors or other preparations which influence the growth of plants. They can also be selective herbicides as well as insecticides, fungicides, bactericides, nematicides, molluscicides or mixtures of several of these preparations, if desired together with further carriers, surfactants or application promoting adjuvants customarily employed in the art of formulation.

The compounds of formula (I) can be mixed with other fungicides, resulting in some cases in unexpected synergistic activities. Mixing components which are particularly preferred are azoles, such as azaconazole, BAY 14120, bitertanol, bromuconazole, cyproconazole, difenoconazole, diniconazole, epoxiconazole, fenbuconazole, fluquinconazole, flusilazole, flutriafol, hexaconazole, imazalil, imibenconazole, ipconazole, metconazole, myclobutanil, pefurazoate, penconazole, pyrifenox, prochloraz, propiconazole, simeconazole, tebuconazole, tetraconazole, triadimefon, triadimenol, triflumizole, triticonazole; pyrimidinyl carbinole, such as ancymidol, fenarimol, nuarimol; 2-amino-pyrimidines, such as bupirimate, dimethirimol, ethirimol; morpholines, such as dodemorph, fenpropidine, fenpropimorph, spiroxamine, tridemorph; anilinopyrimidines, such as cyprodinil, mepanipyrim, pyrimethanil; pyrroles, such as fenpiclonil, fludioxonil; phenylamides, such as benalaxyl, furalaxyl, metalaxyl, R-metalaxyl, ofurace, oxadixyl; benzimidazoles, such as benomyl, carbendazim, debacarb, fuberidazole, thiabendazole; dicarboximides, such as chlozolinate, dichlozoline, iprodione, myclozoline, procymidone, vinclozoline; carboxamides, such as carboxin, fenfuram, flutolanil, mepronil, oxycarboxin, thifluzamide; guanidines, such as guazatine, dodine, iminoctadine; strobilurines, such as azoxystrobin, kresoxim-methyl, metominostrobin, SSF-129, trifloxystrobin, picoxystrobin, BAS 500F (proposed name pyraclostrobin), BAS 520; dithiocarbamates, such as ferbam, mancozeb, maneb, metiram, propineb, thiram, zineb, ziram; N-halomethylthiotetrahydrophthalimides, such as captafol, captan, dichlofluanid, fluoromides, folpet, tolyfluanid; Cu-compounds, such as Bordeaux mixture, copper hydroxide, copper oxychloride, copper sulfate, cuprous oxide, mancopper, oxine-copper; nitrophenol-derivatives, such as dinocap, nitrothal-isopropyl; organo-p-derivatives, such as edifenphos, iprobenphos, isoprothiolane, phosdiphen, pyrazophos, tolclofos-methyl; various others, such as acibenzolar-S-methyl, anilazine, benthiavalicarb, blasticidin-S, chinomethionate, chloroneb, chlorothalonil, cyflufenamid, cymoxanil, dichlone, diclomezine, dicloran, diethofencarb, dimethomorph, SYP-LI90 (proposed name: flumorph), dithianon, ethaboxam, etridiazole, famoxadone, fenamidone, fenoxanil, fentin, ferimzone, fluazinam, flusulfamide, fenhexamid, fosetyl-aluminium, hymexazol, iprovalicarb, IKF-916 (cyazofamid), kasugamycin, methasulfocarb, metrafenone, nicobifen, pencycuron, phthalide, polyoxins, probenazole, propamocarb, pyroquilon, quinoxyfen, quintozene, sulfur, triazoxide, tricyclazole, triforine, validamycin, zoxamide (RH7281).

A preferred method of applying a compound of formula (I), or an agrochemical composition which contains at least one of said compounds, is foliar application. The frequency of application and the rate of application will depend on the risk of infestation by the corresponding pathogen. However, the compounds of formula I can also penetrate the plant through the roots via the soil (systemic action) by drenching the locus of the plant with a liquid formulation, or by applying the compounds in solid form to the soil, e.g. in granular form (soil application). In crops of water rice such granulates can be applied to the flooded rice field. The compounds of formula I may also be applied to seeds (coating) by impregnating the seeds or tubers either with a liquid formulation of the fungicide or coating them with a solid formulation.

A formulation [that is, a composition containing the compound of formula (I)] and, if desired, a solid or liquid adjuvant, is prepared in a known manner, typically by intimately mixing and/or grinding the compound with extenders, for example solvents, solid carriers and, optionally, surface active compounds (surfactants).

The agrochemical formulations will usually contain from 0.1 to 99% by weight, preferably from 0.1 to 95% by weight, of the compound of formula I, 99.9 to 1% by weight, preferably 99.8 to 5% by weight, of a solid or liquid adjuvant, and from 0 to 25% by weight, preferably from 0.1 to 25% by weight, of a surfactant.

Advantageous rates of application are normally from 5 g to 2 kg of active ingredient (a.i.) per hectare (ha), preferably from 10 g to 1 kg a.i./ha, most preferably from 20 g to 600 g a.i./ha. When used as seed drenching agent, convenient dosages are from 10 mg to 1 g of active substance per kg of seeds.
